Respiration

• What are the two types of respiration?

  Aerobic and anaerobic respiration
• Why is energy important in biology?

  It is needed for movement, warmth, and reactions
• What is the process that supplies energy in cells?

  Cellular respiration
• What type of reaction is respiration?

  Exothermic reaction
• What does aerobic respiration produce from glucose and oxygen?

  Carbon dioxide and water
• What is the word equation for aerobic respiration?

  Glucose + Oxygen → Carbon Dioxide + Water
• What happens during anaerobic respiration in muscles?

  Glucose is converted to lactic acid
• What is a key fact about anaerobic respiration?

  It releases much less energy than aerobic respiration
• What is produced during anaerobic respiration in yeast?

  Ethanol and carbon dioxide
• What is anaerobic respiration in yeast called?

  Fermentation
• How is anaerobic respiration in yeast useful for making drinks?

  It produces ethanol for alcoholic drinks
• How does anaerobic respiration help in bread making?

  Carbon dioxide creates bubbles, causing rise
• What are the main differences between aerobic and anaerobic respiration?

  • Aerobic respiration requires oxygen; anaerobic does not.
  • Aerobic produces more energy; anaerobic produces less.
  • Aerobic produces carbon dioxide and water; anaerobic produces lactic acid or ethanol and carbon dioxide.
